An Amazon package of mass ? = 163 kg is released from rest at point A and slides on the frictionless track shown. Point A is ?? = 7.90 ? above the ground. Point B is ?? = 2.50 ? above the ground. Ignore air resistance.

a) Determine the potential energy of the Amazon package at Point A relative to the ground.

b) Determine the speed of the Amazon package at Point B.

c) The Amazon package hits the ground in a perfectly elastic collision. How high does the package bounce into the air (ignoring air resistance)?

Two blocks of masses m1 = 2.00 kg and m2 = 4.00 kg are released from rest at a height of h = 5.00 m on a frictionless track as shown to the right. When they meet on the level portion of the track, they undergo a head-on, elastic collision. Determine the maximum heights to which m1 and m2 rise on the curved portion of the track after the collision. h1 =  m h2 =  m
